Click the Introduction tab. A. Select the small crate from the drop down option.
B. Change the values of the ramp angle to zero so that the surface is horizontal.
C. Adjust the object position to be at 8.0.
D. Now, slowly increase the ramp angle until you reach an angle when the small crate is about to move. Angle = 22 degree.
E. Keeping the same angle, what minimum applied force do you need to move the crate up the inclined plane? Drag the small crate along the direction of the inclined plane and observe the changing values of the applied force. Applied force UZX 15 N 276.
F. Draw the free body diagram.
G. Switch small crate with File cabinet and repeat steps b through f. compare the angle and the applied forces you found for small crate. Which quantity didn't change its value? if so why?
H. Now, change the object to mysterious object and try to find the angle of the ramp in which the mysteries object about to move. Angle = 17.6 degree.
I. What is the mass of the mysterious object?
J. What will be the minimum applied force needed to for the mysterious object to move along the horizontal plane?
